This post will show you to how work around the Youtube view count sorting option, which is mysteriously missing from the list of sort options. To me its a very important sorting option, because the results that appear on top by virtue of the view count is usually the one you are looking for.

Now to work around the problem, simply add video_view_count to the search_sort query string in the search URL.

For e.g. if you have searched for ”music”, the URL would appear as follows …
http://www.youtube.com/results?search_query=music&search_type=

To sort by “Video View Count” add the tag as mentioned earlier, and it should look as follows…

http://www.youtube.com/results?search_query=music&search_sort=video_view_count
